SOLDERING AND BRAZING APPARATUS- Specification of Letters Patent.

Patented Dec. 11, 1906;

Application filed March 20,1906. Serial No. 307,097.

To all whmn it may concern:

Be it known that I, LELAND V. common, a citizen of the United States, residing at Knox City, in the county of Knox and State of Missouri, have invented certain new and useful Improvements in Soldering and Brazing Apparatus, of which the following is a specification.

This invention has for its object to devise simple mechanism for utilizing alcohol, naphtha, or like volatile hydrocarbon in the in dustrial arts for soldering, brazing, welding, and like operations requiring the concentration of a flame upon the work.

As generally practiced an alcohol or spirit lamp has its flame diverted by means of a blowpipe upon the work.

The present invention aims to obviate the blast created by the operator blowing through a tube, this being accomplished by generatin a vapor in a tank or closed receptacle by the application of heat thereto, said vapor being directed through a tube and blowpipe under pressure suflicient to create a jet, such as formed in the ordinary way.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

\Vhile the invention may be adapted to diflerent forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which Figure 1 is a perspective view of an apparatus embodying the invention. Fig. 2 is a sectional view of the tank or generating-re ceptacle, showing the flexible tubing relaced by means of a burner.

The tank or generating-receptacle 1 is preferably of flattened form in order to pro vide an extended surface for the action of a heater, such as a lamp 2, and at the same time providing a comparatively small space for the rece tion of a quantity of alcohol, naphtha, or ike volatile hydrocarbon. The tank or generator 1 is supported by means of a frame or stand 3, which in the preferable construction is closed, so as to form a housing to prevent escape of the heat and to confine the same for a greater length of time.

The heater 2 may be a lamp of any kind and adapted to receive Wood-alcohol or like burning fluid. This lamp is arranged below the generator in position to direct the heat produced by the flame upon the bottom of said generator to the best possible advantage. The tank or generator is of flattened form and circular outline and is provided with a filling-opening 4, closed by means of a screw-cap or in any preferred Way. A tube 5 rises from the top of the generator and is centrally disposed and is adapted to receive either a burner 6 or a flexible tube 7, the latter having a blowpipe 8 fitted to its outer end. A support 9 is removably fitted to the tank and is forked at its upper end, as indicated at 10, to receive the tube 7 and hold the same away from the tank, so as to obviate injury thereto, Which would result if permitted to come in contact with the generator when the latter is heated. The support 9 is stepped in a socket 11, fitted to the top of the generator, and provided in a side wit a set-screw 12 for securing the support when placed in position.

To use the a paratus, a quantity of Woodalcohol or like burning fluid of a volatile nature is placed in the tank 1 through the opening 4, and heat is applied to the tank by means of the lamp 2, whereby the alcohol or like volatile fluid in the tank is converted into vapor and passes oflf through the tube 5 and may be consumed at the burner 6 or at the end of the blowpipe 8. By regulating the vapor of the lamp the quantity of vapor generated in a given time may be varied. Hence the jet at the end of the blowpipe may be regulated to suit the character of Work. \Vhen it is not required to use the ap' aratus and the tank contains a quantity of urning fluid, the tube 5 may be closed by a ea or plug, so as to prevent the Waste of the uid y evaporation, as will be readily comprehended. The support 9, as well as the tube 7, has detachable connection generator. Hence it is possible to store the apparatus in a comparatively small space.

Having thus described the invention, what is claimed as new is- 1. In apparatus of the a generating tank of flattened form and of considerable diametrical extent, and provided with a tube and a socket, a lamp for heating the generator, a flexible tubing provided with a blowpipe and adapted to make IIO with the tank or character set forth, in 5 'connection With the tube of the generator, generator and connected at its outer end to and a support fitted insaid socket and having 1 the bloWpipe, and a support detachably fita fork to receive the flexible tube. l ted to the socket of the generator and having 2.
